Multilayer hollow fiber wound body

Abstract

A multilayer hollow fiber wound body, in which at least a portion of the hollow fibers is formed as helices and/or a portion of the hollow fibers as spirals. The hollow fibers within each hollow fiber ply are disposed at regular intervals to each other. The hollow fibers of adjacent, successive hollow fiber plies cross. The hollow fibers are disposed in the form of at least two superposed and then spirally wound hollow fiber mats, the hollow fibers within each hollow fiber mat being held by several inserted transverse fibers or the like. Within each hollow fiber mat the regular interval between the transverse fibers or the like is greater than the regular interval between the hollow fibers, and none of the hollow fibers has a deflection site, whereby according to the invention the ratio of the regular interval between adjacent transverse fibers within each hollow fiber mat to the regular interval between adjacent hollow fibers within each hollow fiber mat falls in the range of 2 to 40.
